As part of the SHRP2 Tuesdays Webinar Series, TRB conducted a webinar on October 1, 2013 from 2:00 p.m.-4:00 p.m. ET that explored five SHRP 2 projects relating to travel demand forecasting:

This webinar is approved by the American Institute of Certified Planners for 2 Certification Maintenance Credits.
Partnership to Develop an Integrated, Advanced Travel Demand Model with Mode Choice Capability and Fine-Grained, Time-Sensitive Networks (
C10A and
C10B) developed two model sets that link the supply and demand sides of travel forecasting models so that network congestion may inform forecasts of route, time-of-day, and mode choices. SHRP 2 developed one model in partnership with the North Florida Transportation Planning Organization in Jacksonville, Florida. The other model was developed by SHRP 2 in partnership with the Sacramento Area Council of Governments in Sacramento, California. Integrated Advanced Travel Demand Models provide agencies with more behaviorally-based tools for estimating the effects of improving traffic operations, introducing priced roads, improving traveler information, and adding highway or transit capacity.
This webinar also covered three related projects:
- Understanding How Highway Congestion and Pricing Affect Travel Demand (C04) - Traveler’s choice of time-of-day, route, and mode are affected by the cost and reliability of travel. This project estimates a set of equations that add variables to a generalized cost equation allowing models to be sensitive to more variables, including travel time reliability. The results of this research are used in the models developed by projects C10A and C10B.
- The Effect of Smart Growth Policies on Travel Demand (C16) - A quick response model known as SmartGap was developed to estimate the effects of smart growth development patterns on travel demand. It is based on disaggregate inputs like an activity-based travel demand model.
- Primer on Advanced, Dynamic, Integrated Models (C46) - This project is developing a primer to aid managers and practitioners in migrating to activity-based models and evaluating the pros and cons of doing so.
This webinar describes the Integrated Advanced Travel Demand Models, outcomes that agencies experienced after testing the model, and techniques to assist agencies with implementing a similar model in their region. It covers how the pricing and congestion equations are used in a travel demand model and the related quick-response tool for analyzing the travel demand impacts of smart growth development. The webinar will review the current findings of the project and the next steps in implementing the final products.
The intended audience for this webinar is federal, state, and local agencies involved in planning efforts that improve travel demand forecasting. Planning efforts ultimately influence project selection, operation prioritization, and investment decision making. State department of transportation (DOTs) and Metropolitan Planning Organizations (MPOs) are key constituents of this research.
Reports are currently available for
Understanding How Highway Congestion and Pricing Affect Travel Demand (C04) and
The Effect of Smart Growth Policies on Travel Demand (C16). Reports for the other projects will be available at a later date.
Webinar Presenters:
- Tom Rossi, Cambridge Systematics, Inc.
- Stephen Lawe, Marin Outwater, and Joe Castiglione, Resource Systems Group, Inc.
- Robert Donnelly, Parsons Brinckerhoff, Inc.
- Brian Gardner, Federal Highway Administration (FHWA)
- Matt Hardy, American Association of State Highway and Transportation Officials (AASHTO)
Moderated by: Stephen Andrle, Transportation Research Board
Webinar Outline:
- Part 1: Brief overview of SHRP 2 mission, objectives of the Capacity focus area and related SHRP 2 research.
- Part 2: FHWA's perspective regarding the implementation of an Integrated Advanced Travel Demand Model into the travel demand modeling process of MPOs and state DOTs.
- Part 3: Project teams introduce the results, concepts, products, and experience gained from development and testing of these SHRP 2 products.
- Part 4: Question and answer session
The first 90 minutes of the webinar is for presentations and the final 30 minutes is reserved for audience questions.
Learning Objectives:
- To learn about the dynamic interplay of traveler behavior and transportation network conditions, including mode options.
- To learn about the structure of the Integrated Advanced Travel Demand Model.
- To learn about introducing new equations for estimating traveler responses to congestion and pricing
- To learn how to apply the model to existing network processes and procedures.
- To understand how the primer may help users evaluate whether the new model is right for them and how best to apply it within their own organization.
